Oswald Hewlett Sargent
Oswald Hewlett Sargent (5 December 1880, Selly Oak, Worcestershire, England – 4 March 1952, Claremont, Western Australia) was an English-Australian pharmacist, amateur botanist, and plant collector. He was recognized as an authority on Western Australian orchids and studied problems of orchid pollination. Biography As a small boy, Oswald Hewlett Sargent, his parents, and his two sisters emigrated to Western Australia in 1886. His father started a pharmacy at York, Western Australia, where Oswald Sargent was trained. He then attended Perth Technical School, where he was encouraged to study botany by Cecil Rollo Payton Andrews and Alexander Purdie (1859–1905) (whose father was Alexander Callender Purdie). In 1902 Sargent passed his final pharmacy examination and went to work in his father's pharmacy. In 1916 his father died and Sargent inherited the pharmacy. In 1925 he married a pharmacist, Gertrude Victoria Onions, and the couple moved to Perth. He joined in 1924 the Western A ...

Hemiandra Gardneri Habit
''Hemiandra'' is a genus of nine species of flowering plants of the family Lamiaceae and is endemic to Western Australia. Plants in the genus ''Hemiandra'' are shrubs with sessile leaves arranged in opposite pairs, petals with five lobes arranged in two "lips" and the fruit a capsule usually containing four nuts. Description Plants in the genus ''Hemiandra'' are prostrate to medium shrubs with rigid, leathery, sessile leaves arranged in opposite pairs. The flowers have five egg-shaped sepals fused at the base and five petals fused at the base to form a corolla with two "lips". The upper lip short of the corolla is erect with two lobes, the lower lip longer, spreading and three-lobed. The middle lobe itself often has two lobes. The flowers are white, pink or purple, often spotted in the throat. There are four stamens and a single style with two stigmas. The fruit is a capsule usually containing four nuts.

Lamiaceae
The Lamiaceae ( ) or Labiatae are a family of flowering plants commonly known as the mint, deadnettle or sage family. Many of the plants are aromatic in all parts and include widely used culinary herbs like basil, mint, rosemary, sage, savory, marjoram, oregano, hyssop, thyme, lavender, and perilla, as well as other medicinal herbs such as catnip, salvia, bee balm, wild dagga, and oriental motherwort. Some species are shrubs, trees (such as teak), or, rarely, vines. Many members of the family are widely cultivated, not only for their aromatic qualities, but also their ease of cultivation, since they are readily propagated by stem cuttings. Besides those grown for their edible leaves, some are grown for decorative foliage. Others are grown for seed, such as '' Salvia hispanica'' (chia), or for their edible tubers, such as '' Plectranthus edulis'', '' Plectranthus esculentus'', ''Plectranthus rotundifolius'', and ''Stachys affinis'' (Chinese artichoke).

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corolla (botany)
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is described as biseriate. While the ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthers
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains '' microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calyx (botany)
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, a ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus '' Homo'' and within this genus to the species '' Homo sapiens''. '' Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Gardner (botanist)
Charles Austin Gardner (6 January 1896 – 24 February 1970) was an English-born Western Australian botanist. Biography Born in Lancaster, in England, on 6 January 1896, Gardner emigrated to Western Australia with his family in 1909, where they took possession of land at Yorkrakine. Gardner showed an interest in art and botany from youth, becoming engrossed in his state museum's copy of Bentham's ''Flora Australiensis'' (London, 1863-78) and received encouragement from the government's botanist Desmond Herbert and botanical artist Emily Pelloe. After a BSc in Biology, he was appointed a botanical collector for the Forests Department in 1920, and the following year was engaged as botanist on the Kimberley Exploration Expedition, resulting in his first publication, ''Botanical Notes, Kimberley Division of Western Australia'', which gave descriptions for twenty new species. In 1924 he transferred to the Department of Agriculture, and following a departmental re-organisatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watheroo, Western Australia
Watheroo is a small town in the Wheatbelt region of Western Australia. There are 137 residents, according to the . History Land in the area was settled by James Oliver in 1851, the area was surveyed in 1871 and the name Watheroo was charted for the first time. Watheroo is a thriving farming Wheatbelt town, farming livestock and grain. The town was an original station on the Midland Railway Company railway line to Walkaway. The townsite was gazetted in 1907. Railway Following flooding along the Moore River in 1907, the railway lines between Watheroo and Moora were closed for some time when parts of the track were washed away. Rail services were again affected in 1917 when of rain fell in three hours causing more flooding, washways and the railyard in town to be submerged. Etymology The name is Indigenous Australian in origin and was the name of a nearby spring. The word Watheroo is derived from the word ''wardo'' which means little bird or more specifically the willy wagt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environment Protection And Biodiversity Conservation Act 1999
The ''Environment Protection and Biodiversity Conservation Act 1999'' (Cth) is an Act of the Parliament of Australia that provides a framework for protection of the Australian environment, including its biodiversity and its natural and culturally significant places. Enacted on 17 July 2000, it established a range of processes to help protect and promote the recovery of threatened species and ecological communities, and preserve significant places from decline. The Act is administered by the Department of Agriculture, Water and the Environment. Lists of threatened species are drawn up under the Act, and these lists, the primary reference to threatened species in Australia, are available online through the Species Profile and Threats Database (SPRAT). As an Act of the Australian Parliament, it relies for its constitutional validity upon the legislative powers of the Parliament granted by the Australian Constitution, and key provisions of the Act are largely based on a num ...
